Applications
The CRCW08051R00FKEA is commonly used as a current-sensing resistor in motor drive circuits, battery management systems, and power supply feedback networks where a low 1 Ω value is needed to minimize power loss. Its 0805 SMT package is well-suited for automated PCB assembly in consumer electronics, industrial controls, and telecommunications equipment. The 150 V AC rating and ±1% tolerance also make it applicable for signal conditioning and input impedance matching in AC measurement circuits.

Frequently Asked Questions
How can the CRCW08051R00FKEA be used as a current-sensing resistor, and what current levels are practical?
With a 1 Ω value and 0.125 W power rating, the CRCW08051R00FKEA can sense up to approximately 354 mA (limited by I²R = 0.125 W) while producing a 354 mV sense voltage at full load. This suits low-current monitoring in battery charging circuits, LED driver feedback, and microcontroller-based current measurement systems where the sense voltage can be fed directly to an ADC input.
What is the AC voltage rating of the CRCW08051R00FKEA, and does this affect its use in mains-connected circuits?
The CRCW08051R00FKEA is rated for 150 V AC operating voltage. This makes it suitable for low-voltage AC measurement and signal conditioning circuits, but it should not be used directly across mains voltages of 120 VAC or 230 VAC without proper series current limiting. The 150 V AC rating provides some margin for low-voltage AC applications in industrial signal interfaces.
How does the 0805 package size of the CRCW08051R00FKEA compare to smaller resistor packages for current sensing?
The 0805 package (2 mm × 1.25 mm × 0.5 mm) offers a larger thermal mass and higher power dissipation than 0603 or 0402 alternatives. For current sensing applications, this is advantageous because the 0805 size handles 0.125 W continuously — roughly 25% more than a standard 0603 at 0.1 W — enabling higher sense currents or lower thermal rise at the same current level, improving measurement accuracy over temperature.
